There is a lot of paddling in CO. Not too much close to Co Springs though. There is a local paddling club that you might want to hook up with: Pikes Peak Whitewater Kayak Club
Probably the most convienant river for you to access will be the Arkansas. The Ark has everything from class V creeking at it's headwaters to mellow I-II fishing floats.
Another river that is pretty close to you is the South Platte. You have the North Fork South Platte which has the IV-V Bailey Canyon run, and the III-IV Foxton stretch. The South Fork of the South Platte has the III-IV Elevenmile Canyon, the class V Cheesman Canyon and the class II Deckers stretch. Below the confluence of the 2 is Waterton Canyon a fun (but short) stretch of III-IV.
There are a few playparks nearby as well. The closest to you will be Pueblo and Canon City....but the best features are at Salida and Buena Vista....which also happen to be the locations of 2 of the best whitewater festivals in the state, Paddlefest and Fibark.
There is more reading material on the different drainages and what they contain at both:

I hope this helps, welcome to Colorado!
